Catalytic Oxidation of CO and VOC in Flue Gas of Coffee Roasting Machines

open access: yesChemie Ingenieur Technik, EarlyView.
Platinum‐coated cordierite monoliths effectively oxidized CO and VOC in coffee roasting exhaust with higher Pt loadings lowering light‐off temperatures. Scaled up 90 g/ft3 catalyst in a 5 kg roaster achieved 96% CO and around 78% VOC conversion at 350°C, highlighting stable operation requires flue gas temperatures ≥350°C.
